A substrate processing method comprising steps for forming a copper film on a surface of a substrate. Particularly disclosed are synthetic, isolated polypeptides capable of binding CEA, which is overexpressed in adenocarcinomas of endodermally derived digestive system epithelia and fetal colon. Devices generally include an elongate catheter having at least one tensioning member and at least one tensioning actuator for deforming a distal portion of the catheter to help it conform to a valve annulus. The seamless outer perimeter providing a seamless folded continuity between the two sides of the pad-type filter in the form of a plurality of fold lines which, as connecting segments beginning and ending at the same point, define the seamless outer perimeter. 5, \u2003\u2003with definitions:I=Re\u2212Re;II=Re\u2212Re;III=Rth\u2212Rth; andIV=Rth\u2212Rth,wherein Re, Re and Re are in-plane retardations measured with lights of wavelength of 450, 550 and 650 nm, respectively; and Rth, Rth and Rth are retardations in a thickness direction of the optical film, which are measured with lights of wavelength of 450, 550 and 650 nm, respectively. The method may include cutting a self-adhesive tape into a strip or other elongate shape and stretching it to obtain at least some tension.
